ProofMint - Decentralized IP Publishing dApp

ProofMint is a Web3 application for publishing and verifying intellectual property on the Flare blockchain. Users can write research, generate SHA-256 cryptographic proofs, check originality via Flare Data Connector, and publish tamper-proof records on-chain.

Project Structure

``` /contract - Hardhat smart contract project /client - React + TypeScript frontend ```

Quick Start

1. Deploy Smart Contract

```bash cd contract npm install cp .env.example .env

Add your private key to .env

npm run deploy:local ```

2. Run Frontend

```bash cd client npm install npm run dev ```

The app will open at http://localhost:5173

Features

• Publish Posts: Write research/IP and publish to blockchain
• SHA-256 Hashing: Client-side cryptographic proof generation
• Originality Scoring: Check content originality via Flare Data Connector
• Smart Account Integration: Secure on-chain publishing with wallet signing
• Post Feed: View all published posts with verification proofs
• Proof Cards: Display content, originality score, and blockchain timestamp

Tech Stack

• Frontend: React 18 + TypeScript + Tailwind CSS + Vite
• Blockchain: Solidity + Hardhat + Ethers.js
• Network: Flare Coston2 testnet
• Web3: MetaMask wallet connection + Smart Accounts
